The 6721 has a 16" heavy barrel (HBAR), CAR handguards, 1x9 twist, the lower is marked AR15A3 with restricted markings on the right side of the lower. (last one we had had a shrouded AR15 carrier)
The 6920 has a 16" M4 profile barrel, M4 handguards, 1x7 twist and it's lower is marked Colts M4 Law Enforcement carbine and restricted markings on the right side of the lower. (M16 carrier)
